Combining elements from football, soccer, and dodgeball, G-Ball is a three-on-three arena battle in which floating athletes compete to score goals while fending off opponents using defensive equipment. The game in its current state includes online play and unlockable Steam achievements, and Oculus Rift support is planned in a future update.

G-Ball is the first game in NASA's Starlite Astronaut Academy series, which will soon expand to include a number of different space-themed activities and simulations. G-Ball is available at a 25 percent discount in its debut week, and is currently priced at $2.99.
